ERP Program Manager at Fiserv
The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP are followed and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of available transition approaches based on business objectives, technical feasibility and SAP Best Practices.
Technical Readiness Assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points and infrastructure readiness for SAP S/4HANA.
Business Process Impact Analysis – reviewing the latest business process documentation to define the scope and effort required to implement the necessary functions in SAP S/4HANA and to identify opportunities for process optimization.
Roadmap for Non-SAP Systems and Applications – assessment of third-party and legacy applications regarding their integration with SAP S/4HANA and recommendation of consolidation, migration or replacement strategies.
Deployment & Implementation Planning – defining a phased approach for implementation, including project schedules, risk mitigation strategies and key milestones aligned with business priorities.
This transformation takes place in phases: the Discovery phase leads to the Explore phase, which is followed by the Design phase and finally implementation.

About the technology
Fiber backbone technology
FDDI, short for Fiber Distributed Data Interface, is a standards-based networking technology designed for high-speed local and metropolitan area backbones. It uses fiber-optic links and a token-passing protocol to connect workstations, servers, bridges and routers. Its dual-ring design can maintain communication after a single link or station failure.
Rings and resilience
An FDDI network normally uses a primary ring for data transmission and a secondary ring for protection or additional capacity. Stations, dual-attached stations and single-attached stations connect through concentrators. Wrap and bypass behavior help preserve service when a cable segment or interface becomes unavailable.
- Map dual-ring and concentrator layouts
- Plan single-mode or multimode fiber segments
- Define fault isolation and recovery paths
- Document station, bridge and router connections
Protocol ecosystem
FDDI specialists work with the physical and data-link specifications associated with ANSI X3T9.5, including token timing, frame handling and ring management. Projects may also involve FDDI-2, Copper Distributed Data Interface, Ethernet, Fast Ethernet, SONET or ATM, especially when older backbones connect to newer infrastructure.
Where it still matters
FDDI is mainly found in established campus, industrial, telecommunications and public-sector environments where stable fiber infrastructure remains in operation. Companies in Germany may need specialists to maintain inherited networks, integrate replacement equipment or plan a controlled migration without disrupting critical systems.
- Assess legacy backbone dependencies
- Replace failed interfaces and concentrators
- Validate ring continuity and optical levels
- Connect FDDI segments to Ethernet infrastructure
When to hire a freelancer
Bring in freelance FDDI expertise when internal teams lack access to compatible test equipment, historical network documentation or practical experience with ring failures. Specialists can perform discovery, trace physical paths, analyze token and link behavior, create migration plans and support on-site work while coordinating remotely with operations teams.
What strong specialists bring
A strong professional understands both the standard and the physical network. They can distinguish an optical fault from a station, concentrator or configuration problem, read legacy diagrams, and use analyzers, optical test tools and vendor diagnostics safely. They also explain risks clearly and leave precise records for future maintenance.
For Germany-based projects, collaboration may combine remote planning with visits to data centers, campuses or industrial sites. Clear documentation in English or German can be important when several teams share responsibility for an aging backbone.
Frequently asked questions
Key details about FDDI, drawn from the questions we get asked most.
FDDI is used to connect servers, workstations, routers and bridges across resilient fiber-optic backbones. Its dual-ring architecture was suited to campus networks, industrial sites and other environments where fault tolerance and predictable access were important.
Fiber Distributed Data Interface uses token passing and ring-based resilience, while modern Ethernet usually relies on switched links and is easier to source and extend. FDDI can remain practical when an existing backbone, compatible equipment or operational procedure depends on it, but migration may be preferable for a new installation.
FDDI work often requires optical fiber testing, structured cabling knowledge, Ethernet integration and routing or switching fundamentals. Experience with legacy network documentation, protocol analyzers, concentrators and vendor-specific interfaces is also valuable.
A freelancer working with FDDI should have handled real ring diagnostics, optical faults and equipment replacement rather than only studied the specification. The right level depends on the assignment: documentation may need less field exposure than a recovery or migration involving critical links.
FDDI projects can often begin remotely with topology reviews, configuration analysis and migration planning. Physical tracing, optical measurements and hardware replacement usually require on-site access, so teams in Germany should agree early on travel, site access and documentation language.
Ask an FDDI specialist to explain how they would isolate a broken ring, validate a concentrator and protect service during a change. Strong answers cover physical inspection, test evidence, fallback steps and clear network documentation rather than relying on assumptions.
FDDI-2 extends the original FDDI approach with support for circuit-switched and packet-switched traffic on the ring. It is less commonly encountered than standard FDDI, so a freelancer should confirm the installed specification and equipment before proposing troubleshooting or replacement work.
FDDI is no longer the usual choice for new general-purpose networks, but it can still matter in inherited campus, industrial, telecommunications or public-sector infrastructure. A specialist can assess whether continued maintenance, a staged Ethernet migration or full replacement best fits the system's risks and operational constraints.
